This recipe is for butter that is easy to spread straight from the refrigerator. It is similar to the spreadable real butter spreads you find in the grocery store - only it's much less expensive. It contains less saturated fat than butter. What I like best about this recipe is that I can use my favorite unsalted, organic, cultured butter. For the oil, I like to use an expeller pressed safflower oil with added vitamin E. It has a very mild flavor. Sometimes, I also like to use an 80% canola 20% olive commercial blend for the oil. 100% Olive oil can be used, but the finished product tastes strongly of olive oil. I like how this butter works in sautes, too. Due to the addition of the oil, it doesn't burn as easily as straight butter does. The butter will become very soft (almost runny) if left out of the fridge. Be sure to return it straight to the cooler when you are finished with it.
